Pros
Great respect for work/life balance. Managers, at least seem, to care about the happiness of their reports and definitely want to try and make sure you're doing work that you enjoy. Company implemented "Invest in Yourself Days" where we were allowed to essentially do whatever in order to focus on ourselves. Some people literally used the day to meditate or have a good work out. Others used it to learn something new that they wouldn't usually get to use in their typical day-to-day. Definitely a place where you can come and retire. Competitive pay and job security as long as you do your job of course. Extremely smart people work here and you can learn a lot from the people around you.
Cons
Like any corporate company, the politics game is heavy here. If you want a promotion you have to practice "influence" instead of just showing strong competency and results. The loudest and most vocal person is generally the one driving the discussion which I think leads to other team members from not wanting to participate or even caring to.
